Sweeney, who sets the agenda in the Senate where Christie's nomination must win approval, did not immediately make clear how the governor's naming of Judge David Bauman was like Trump. Sweeney leads the Democrat-led state Senate.

Christie nominated Bauman this week to fill a vacancy. Sweeney says he won't allow the nomination to go forward because it would swing the party makeup of the court too heavily in Republicans' favor.

Christie disagrees and counts one Republican-appointed justice already on the court as an independent.

The disagreement is playing out as U.S. Senate Republicans say they won't consider President Barack Obama's nominee to succeed Justice Antonin Scalia.
